American Gas & Chemical Co. Ltd products

CGT-501 Available for all combustible and many toxic gases. (See below for a complete list) Available in rechargeable (NK) and non-rechargeable (AK) versions. Packed in handy carrying case. CGT-701 Rechargeable detector for nitrogen dioxide, ozone, chlorine, fluorine, bromine and other halogen gases.

The SBG-200 is an affordable solid-state completely self-contained monitor capable of detecting a variety of toxic and flammable gases and vapors. Several sensors are available which allow it to be calibrated to alarm at gas concentrations well below their lower explosive limit or OSHA ceiling.

They are a Safe, Sure, Fast, Easy, Sensitive Low Cost Way to Find Hidden Defects. Penetrants highlight flaws and leaks that are open to the surface and are too small to see by normal visual inspection. Inspection penetrants show the presence, location, nature and size of defects. Penetrants are convenient. They can travel anywhere in the field or be used where work space is limited. Penetrants can be used if the product being tested is very large or complex. Inspection penetrants are used indoors and outside. Inspection penetrants are recommended for the production inspection of large volumes of critical components where reproducibility is essential. Inspection penetrants are capable of detecting leaks as small as 1x10 -4 Std. cc/sec.

Shot Peening improves metal and weldment resistance to fatigue, stress corrosion cracking and galling. To provide this benefit, it is important that shot peen coverage be uniform and complete. A liquid tracer (Fluoro-Finder III) provides a coating which is removed at a rate proportional to peening coverage, providing visual feedback on the uniformity and completeness of peening coverage. Fluoro-Finder III, has a pigment which fluoresces under ultraviolet light making the determination of the degree or percentage of coverage quick, easy and foolproof. Use of this tracer eliminates the need for 200-percent coverage in order to be assured of complete peening.

Thin film bubble testing is the most common and one of the most reliable methods of detecting and locating leaks. Thin film leak testing has many inherent advantages: It is easy to use and requires little operator training. It is inexpensive to use and not subject to break down like complex instrumentation. It operates immediately and continues to give indications. It can be extremely sensitive, finding leaks down to 1 x 10-6 (.000001) standard cc/second. The equivalent of losing a pound of Freon every 2,700 years.

By lowering the surface tension and increasing the wetting ability of water, a leak in a pressurized immersed vessel will generate a steady stream of tiny bubbles instead of an occasional larger bubble as with untreated water. Small leaks will produce bubble indications that are impossible with normal water. The CIM Immersit series will not foam, will not support bacteria growth and are formulated to prevent corrosion. Although their use is recommended with deionized  or distilled water, they are chelated to be compatible with mildly hard water. Immersit additives are biodegradable. They meet the requirements of ASTM E515 Sec 8 on Immersion Leak Testing.

The Sonic 3000 is a hand held, battery powered ultrasonic sound detector. It translates inaudible, ultrasonic frequencies, into a variety of recognizable sounds and meter readings. The Sonic is capable of locating liquid and gas leaks as well as diagnosing a number of maintenance problems. The Sonic 3000 exceeds the requirements of the ASTM Standard Method of testing using ultrasonics.

Color Change is Shown in the Presence of Specific Toxic Gases. Easy to Use: Can be used by anyone. No hygienists or technicians required. Lightweight - reusable badge weighs 1/4 ounce. Badges and monitors are immediately ready for use. No activation required. Cumulative and one time exposure results are easily obtained and tracked.

Colormetric detectors are rapid leak detectors and inexpensive to use.  They react chemically with minute leaks causing a visible color change in the developer. They can be used to detect leaks up to 1x10-7 Std cm3/s.

This tracer is a concentrated (immediately miscible) liquid dye, operating in the visible mode - no special equipment needed to see results. Developed for water systems study, this tracer is ideal for leak testing large systems or pipelines. Biodegradable - can be diluted up to four ounces per 500 gallons. (ASTM 11.3.2.2 & ASTM 11.3.2.3 Visibility Enhancers). Available in 4 oz, gallon, 5-gallon and 55-gallon packages.
